Wearing spectacles and keeping them in place, especially while doing physical work such as running, would be much easier now -- thanks to Googleâ€™s latest patent.

The patent outlines a system built into a wearable device like Google Glass, that uses motors and motion detectors to automatically tighten or loosen the spectaclesâ€™ arms depending on what the wearer is doing, Quartz reported.

In Googleâ€™s idea, the new spectacles would have an actuator -- a little motor for controlling movement -- in each arm that could bend the arms in or out as needed, rather like the way a bendy straw works.

When the spectacles detect that their wearer is bobbing up and down at an increased rate -- while running, for example -- the arms contract to grip the wearerâ€™s head.

The actuators could also help solve the one-size-fits-all approach that many spectacles have to fitting -- if the specs are too wide for someoneâ€™s face, the actuators could automatically resize them so that they fit snugly.
